Which action goes against the 3rd Commandment?

• A. Deliberately choosing to miss Mass on Sundays/Holy Days of Obligation for no legitimate reason
• B. Working or going to sports instead of Mass
• C. Not resting
• D. Not fasting/having a clean+pure heart before receiving Communion

Answer: (A)

The key idea here is sanctifying the Lord’s Day through worship. The Third Commandment calls believers to set Sundays and Holy Days apart for God by participating in worship, especially the Eucharist, and by resting from unnecessary work so the day remains holy.

Deliberately skipping Mass on Sundays or Holy Days without a legitimate reason directly disobeys that obligation. Attending Mass is the primary way Catholics fulfill the command to sanctify the day, so missing it for no valid reason undermines the core practice the command requires.

The other options touch on related ideas but aren’t as direct a violation of this command. Not resting on Sundays relates to the day’s rest, but the command’s worship obligation is the distinctive element. Not fasting or having a clean heart before receiving Communion concerns the proper preparation for receiving the Eucharist, not the basic duty to participate in the Sunday worship itself.
